Abstract
The present invention provides a transflective blue-phase liquid crystal display panel comprising a first substrate, a second substrate, and a liquid crystal layer, wherein the first substrate and the second substrate comprise a plurality of subpixels, and each subpixel comprises a reflective region and a transmissive region, the liquid crystal cell gap of the reflective region is equal to that of the transmissive region, a plurality of first common electrodes and first pixel electrodes that are alternately arranged at equal intervals are set on the part of the second substrate; a second common electrode is set on the part of the first substrate, a second pixel electrode having a via hole at its center is set on the part of the second substrate. In the invention, an alignment layer can be omitted; the display visual angle can be enlarged by designing an electrode structure, and the contrast ratio can be improved, thereby a single cell-gap structure can be attained.
